dc.description.abstractIn this study, the AMR-WB+ audio codec is implemented, in real-time, using the Intel 400MHz Xscale PXA250 with 32bit RISC processor ARM9E-J core. The assembly code for ARM9E-J Core is developed through the serial process of C code optimization, cross compile, assembly code manual optimization and adjusting the optimized code to Embedded Visual C++ platform. C code is trimmed on Visual C++ platform. Cross compile and assembly code manual optimization are performed on CodeWarrior with ARM compiler. Through these four development stages, codes for both ARM EVM board and PDA are produced. The implemented codec is evaluated using 16 test vectors given by 3GPP. Through this evaluation the bit-exactness of the S/W is verified. The average complexity of AMR-WB+ codec is 174.10MCPS for encoder and 36.78MCPS for decoder. In case of static link library (SLL), required memories are 334.79 Kbytes of ROM and 42.24 Kbytes of RAM.-
